Synthesis of Unsymmetrical Δ4,4'-2,6-Diphenyl-4-(thiopyranyl)-4H-pyrans

Unsymmetrical Δ4,4'-tetraphenyl-4-(thiopyranyl)-4H-pyran 17 and related compounds have been synthesized.The reversal in the polarity (umpolung) of 2,6-diphenylpyrylium salt 13 is achieved by the synthesis of the Wittig-Horner reagent (11) of di

Bipyrans for Electrochemical Studies. Preparation of Polyene-Separated Bipyrans and Bithiopyrans

4,4'-(But-2-ene-1,4-dienylidene)-bi-4H-pyran and thiopyran derivatives were prepared by allowing the anion prepared from diethyl 4-(2,6-diphenyl-4H-pyranyl)phosphonate to react with 4-pyranylidene butenaldehydes or the corresponding thiopyranylidene aldeh
